Displacement of Guar Gum in Porous Media to Control Water Mobility
Porous Media Water Mobility
2008/10/28
Oil recovery is made, firstly, by primary (natural energy or pumping) and by secondary (water flood) methods. However, these conventional methods extract only around 50% of the original oil in place. ...
